Abstract
Based on a multi-year research (1993-2016), an assessment of the state of the environment in the area of development of oil and gas condensate fields in the north of Western Siberia (YaNAD) is given. The content of petroleum hydrocarbons, PAHs and heavy metals (Cu, Zn, Fe, Pb, Cd, Ni, Co, Cr, Ba, Cd and Mn) was determined in soils, natural waters, bottom sediments and in indicator plants - Larix sibirica , Betula nаnа , Salix lanаta , Ledum decumbens , Vaccinium vitis-idaea , V. uliginosum and Cladonia alpestris. Using the calculation of the coefficients of interspecies conjugation of plants, pleiads of species corresponding to the ecological conditions of habitats and the intensity of the technogenic impact were identified. A set of indicators for assessing the transformation of natural complexes under the influence of oil and gas extraction is proposed.
